IMPROVEMENT IN GATES.

SPECIFICATION.

l, NATHAN B. HELM, of Alden, in the coun ty of McHenry and State'qof Illinois, have inlvented anew and useful Improvem ent in Gates,

of which the following is a specification:

The present invention relates to an improvement in that class of gates which is arranged to be opened and closed by persons in carriages and on horseback without alighting;

tachments; Fig. 2, a planv or top view of the frame-work and mechanism for operating the gate.

A represents the hanging-posts; D, the jamb-posts; and C E, the gate, allot' which `are constructed in the ordinary manner, and,

therefore, need no particular description. B represents a post, set nearly at right angles to the gate C E, and at such a distance from the hanging-post A as will correspond to the length of the gate, so that when the latter is open it will be fastened by a catch, G. On the tops of the posts A B is rigidly fastened an obtuse angular frame, m n, which is made in the form shown, that the cords, hereinafter described, may be supported in suitable positions to open and shut the gate C E. a represents the cord which closes the gate, and it is attached to the gate at d,'and passes over the pulleys g c and is attached to a weight, f.

The cord for opening the gate on one side is shown at X, and it is attached to a cord, y, and is put over a pulley, N, through a loop or eye, c, and over a pulley, K, on one end of the frame-Work n. This arrangement is such that by drawing on the outer end of cord X the latch F will be rst raised up in its loop, after which the gate will be swung open and fastened to post B by means of a latch, G, so as to let a vehicle pass through; after which a cord, T, passing through eyes S O P Q and an eye under the end of n, can be drawn upon so as to swing a weighted lever, H, and raise a latch, G, by means of a connecting-cord or rod, h, Fig. l. This will loosen the gate from the post B, and the weight f and cord a will carry it to the jamb-post D, to which it is fastened by latch F. The means for opening the gate from the opposite direction consists of a cord, b, which passes over a pulley, T', through eyes t r on the frame-piece m, over a pulley, M, in a sheave-bloclr, w, and fastens to the saine cord y that the cord X fastens to. By drawing on the cord b the gate is opened in the same manner as it is by drawing on the cord X, and by drawing on a cord, U, the 1ever is swung on its pivot e so as to raise the latch G in the same manner as by drawing on the cord T.

The object of the. lever H is to readjust the cords T U after they have been drawn upon to raise the latch G; and this adjustment will be the better accomplished if the lever H be operated by strong iiexible wire running through the loops on the frame 'n m.

If H were not a weighted lever, the friction I of the cords U T might be so great as to hold the latch G up when once raised.

Having thus described my invention, I claim- In the construction of automatic gates, the weighted lever H, in combination with the latzh G, gates C E, and cords UT, as specifie NATHAN B. HELM.
